LIQUID-DISPENSING APPARATUS.

T 0 all whom it may concern:

Be it known that I, RALPH WV. ELLIOTT, a citizen of the United States,residing at Antioch, in the county of Contra Costa and State ofCalifornia, have invented new and useful Improvements inLiquid-Dispensing App aratus, of which. the following is aspecification.

The object of the present invention is to provide a convenient, rapid,and accurate apparatus for measuring liquids, when dispensing the samefor sale or for other purposes.

In the accompanying drawing, Figure 1 is a side view 'of the apparatus,partly invertical section,showing the parts in theposition in which theliquid is being measured,

and Fig. 2 is a similar view showing the parts 'in the position when themeasurement has been completed.

Referring to the drawing, 1 indicates a pipe up which the liquid isforced by a pump or by gravity, as may be found convenient. From thispipe the liquid passes through a valve opening 2, controlled by a valve3, and thence to a pipe 4, the lower end of which is open, and fromwhich they liquid drops into a receptacle 5. Extending from the bottomof said receptacle is a pipe 6, controlled by a cock 7, by means ofwhich the liquid may be drawn o'lf'from the receptacle. Said receptacleis suspended by means of chains 8 from a scale beam 9, fulcrumed at 10upon a suitable extension or support 11 secured upon the pipe 1. Thelong arm of said scale beam is suitably graduated, as shown at 12, toindicate different quantities by volume. However, these graduations mayindicate weight, if desired. Above the scale beam is secured a slide rod13, which extends in the same vertical plane as the scale beam, but isslightly inclined downwards towards its short arm. Upon said slide rodcan slide a weight 1 1, which has a downward y extending pointer 15. Atthe end of its sliding movement the weight impinges against a weight 16upon the slide rod, between which weight and a stop 17 adjustablysecured upon the slide rod When the scale beam is tilted, its descendingshort arm depresses the head 19 of the valve 3, and closes said valve,preventing the passage of any liquid from the pipe 1 into thereceptacle.

The apparatus is used in the following manner: The stop cock 7 beingclosed, the weight 1 1 is moved along the slide bar to bring the pointeropposite to the mark indieating the quantity of liquid which it is de-Specification of Letters Patent.

sired to dispense, as, for instance,}; gallon. The scale beam is nowlevel and the valve 3 is therefore open. This allows the liquid to flowinto the receptacle, and it continues to so flow until such a weightthereof has entered the receptacle as will counterbalance the weight 14at the point at which it has been placed. As soon as the weight of thereceptacle is sufficient to overcome the weight, the receptacle falls,thereby tilting the scale beam and closing the valve 3, preventing thepassage of any further liquid. The liquid can then be withdrawn from thereceptacle by opening the stop cock. After the liquid has been all drawnoff, the stop cock is closed and the apparatus is again ready for use. i

The weight 16 serves two purposes. It acts as a buffer to yieldinglyreceive the impact of the weight 14. at the end of its sliding movement,but its principal object is for the purpose of adjustment of the scalebeam for liquids of different specific gravity. It is evident that whenmeasuring liquids by volume, since the scale beam is tilted by theweight of the liquid supplied to the receptacle, means should beprovided for adjusting the scale beam to correspond with the differencesin the weights of liquids of varying specific gravities. Provision ismade for this purpose by means of the weight 16, which can receptaclebeing supported on said scale beam at one side of its fulcrum, acounterbalance weight, slidably supported on said slideway, and meanswhereby the movement of the scale beam controls said valve,substantially as described.

2. In an apparatus of the character described, the combination of ascale beam, a receptacle attached to said scale beam, a slide rodsecured to said scale beam, and inclined thereto, a weight slidable uponsaid rod and having a pointer directed towards said scale beam, meansfor supplying material to said receptacle, a valve controlling saidmeans, and means whereby the movement 'of the scale beam controls saidvalve, substantially as described.

3. I11 an apparatus of the character de scribed, the comblnation ot ascale beam, a receptacle attached thereto, a pipe for drawing off liquidfrom the receptacle, a stopcock for the latter pipe, a pipe forsupplying the liquid to the receptacle, a valve for controlling saidlatter pipe, a slide rod connected to said scale beam, a weight slidableon said. rod, said scale beam contacting with the valve to control theliquid supply and close the same when the scale beam is tilted,substantially as described.

4. In an apparatus of the character described, the combination of ascale beam, a receptacle attached thereto, a pipe for drawing o'il'liquid from the receptacle, a stopcock for the latter pipe, a pipe Forsu ')plying the liquid. to the receptacle, a valve for controlling saidlatter pipe, a slide bar connected to said scale beam, a weight slidableon said. rod, having a pointer directed towards said scale beam, saidscale beam contacting with. the valve to control the liquid supply andclose the same when the scale beam is tilted, substantially asdescribed.

5. In an apparatus of the character described, the combination of ascale beam, a receptacle attached thereto, a pipe for draw ing o'f'l'liquid from the rece .)tacle, a stopcock for the latter pipe, a pipe forsupplying the liquid to the receptacle, a valve for controlling saidlatter pipe, a slide bar connected to said scale beam, a weight slidableon said rod, a s ring-controlled. bull'er against which the weight canimpinge at the end oi its sliding movement, said scale beam contactingwith the valve to control the liquid supply and close the same when thescale beam is tilted, substantially as described.

6. In an apparatus of the character described, the combination of ascale beam having a slideway, a receptacle supported by said scale beam,means for supplying a material. thercto, a valve for controlling saidsup ply, a counterbalance Weight slidable on said slideway, meanswhereby the movement oi" the scale beam. controls said valve, and anadjusting weight, adjustably supported by the scale beam, to adjust thesame [or vary ing specific gravities, substantially as described.

7. In an apparatus of the character described, the combination ol' ascale beam, a receptiu'le attached thereto to oscillate said scale beamby its weight and the weight of its contents, a movable counterbalanceweight upon. said scale beam, means for supplying material to saidreceptacle, a valve arranged to close said supply, means actuated by thetilting of the scale beam to close said valve, an adj usting weight, andmeans for adjustably and resiliently supporting said weight in the pathoi the movable weight, to be impinged upon by the latter at the end ofits movement upon the tilting of the scale beam, substantiall asdescribed.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
